Samsung Dryers, like any other electrical appliance, can face a whole lot of issues and some of these can be worrying as well. Dryers are actually one of the biggest reasons behind home fires but modern dryers have a thermal fuse which helps prevent this exact thing from happening.
But sometimes this fuse might keep blowing without any reason or for reasons which you might not know about. This can get very irritating and even scary sometimes. Let’s take a look at some of the reasons why your Samsung dryer’s fuse keeps blowing.
Some of the most common reasons for your Samsung dryer’s thermal fuse to blow can be a blocked exhaust vent, an issue with the thermostat and the heating element, a blocked lint screen or the thermal fuse might simply be bad.
You can easily check to see if any of these reasons are behind your issue.
Let’s take a look…
Why Your Samsung Dryer’s Thermal Fuse Keeps Blowing
The thermal fuse does one job, it prevents the appliance from overheating which can further create short circuits and house fires. As soon as the temperature inside the dryer goes past a certain limit, the fuse blows out.
Some of the Samsung dryer models will show a code ‘HC’ which represents a high temperature heating check. If this is the case, then either the internal temperature is rising too much, or the temperature sensor might be bad.
This rise is temperature can be due to a clogged exhaust vent or lint screen which is not letting the hot air leave the appliance.
To check the lint screen or the exhaust vent, open the back of the appliance to access it. If the lint screen is covered by a lot of debris, it can prevent proper air circulation. This can raise the temperature inside the appliance which causes the thermal fuse to blow out.
Simply clean this screen once and wash it properly to solve this issue.
A similar issue can happen with the thermal fuse itself. Sometimes the lint escapes the filter and collects near the thermal fuse. This can increase the heat near the fuse and cause it to blow out.
If neither of these reasons seem to be the problem, then there might be some other reason for the appliance temperature to be going up. In this case you will have to call a professional to get it checked out.
Issue With The Thermostat And The Heating Element
The thermostat in your dryer is meant to control the heat generated inside the dryer. This component in combination with the heating element regulates the amount of heat generated.
The heating element provides the heat while the thermostat tells the heating element to switch on and off depending on the internal temperature.
An issue with either of these components can lead to an excessive amount of heat inside the appliance which in turn will blow out the thermal fuse. The thermostat is usually located below the thermal fuse.
How To Check If Your Thermal Fuse Is The Issue
If you did not see any obvious problems with either of these components or any lint build-up on the fuse or the lint screen, then you can perform a simple test to see what the issue is.
First unplug or disconnect the dryer from the power source for safety. Take both the wires going into the thermal fuse out and join them together using an electrical tape. This will bypass the thermal fuse for the time being.
Make sure you reconnect these wires to the fuse after this test as it is very important for your and your house’s safety.
Turn the dryer to a position so you can record the temperature of the air being blown out. Use a thermometer to do so. The next step is to re-assemble the dryer to conduct this test. Start the dryer on a high setting and a medium load.
The dryer temperature should reach around 150F before going down by 20-25F and then the heating element will switch on again to increase the temperature to 150F. if the temperature exceeds this, there is a problem with the thermostat or the heating element.
In this case you will probably need to replace both the components at once. If the temperature was within the stipulated range, then there is an issue with either the control board or the thermal fuse.
You can also conduct a grounding test on the thermal fuse to check if it is working properly. You can simply use a multimeter and connect both the poles of the fuse to the tester. If there is a current flow through the fuse, then it should be working properly.
Issues With The Control Board
The control board is the brains of the appliance and is responsible with regulating all of the different function in the device. But there can be a failed relay on the control board which sends excessive power to the dryer.
This can also lead to the thermal fuse overheating. In this case all you can do is call a professional to get it checked and most probably you will have to get the board replaced.
A faulty control board can also lead to a false ‘HC’ error on your device.
Be very careful while dealing with electrical appliances, make sure you are taking all of the necessary precautions and the device is switched off and plugged out before you open it.
A thermal fuse is an essential part of your dryer and any potential issue with it can be worrying.
You need to make sure the issue is resolved before you start using the device again.
